Underfloor heating is a popular choice when renovating, as it provides pleasant and even heat throughout the room. Installing underfloor heating during a renovation requires careful planning and the right work steps. In this article, we go through the underfloor heating installation process step by step.

1. Planning

Before starting the installation work, it is important to plan the underfloor heating system carefully. In the planning phase, the following factors are taken into account, among others:

  • Type of heating system (water circulation or electric)
  • The need for heating power
  • Floor materials and their compatibility with underfloor heating
  • Size and shape of the room

During the planning phase, you should consult a professional who can evaluate the most suitable system and its requirements.

2. Dismantling the old floor

Before installing the new underfloor heating, the old floor must be dismantled. This step includes:

  1. Removing the old floor material
  2. Dismantling any old heating systems
  3. Checking the platform and leveling it if necessary

It is important to ensure that the substrate is level and clean before installing a new underfloor heating system.

3. Installation of the heating system

The actual floor heating system is installed next. The installation steps vary slightly depending on whether it is water-circulating or electric underfloor heating.

Water circulation floor heating

  • Install the insulation boards on top of the floor. The insulating plates prevent the heat from escaping downwards.
  • Place the heating pipes on top of the insulation boards according to the plan. Pipes are usually fixed with fixing bands or rails.
  • Test the tightness of the pipeline before pouring concrete.
  • Choose underfloor heating concrete over the pipes and let it dry properly.

Electric floor heating

  • Install the insulation boards on top of the floor.
  • Lay the heating cables or mats on top of the insulation boards according to the plan.
  • Test the functionality of the heating cables before covering the floor.
  • Apply the screed or floor material over the heating cables and let it dry.

4. Finishing the floor

Once the underfloor heating system has been installed and tested, you can move on to finishing the floor. This step includes:

  1. Installation of the selected floor material (e.g. tiles, parquet, laminate)
  2. Finishing of moldings and edges
  3. Heating system adjustments and installing thermostats

It is important to make sure that the floor material is compatible with underfloor heating and that it is installed according to the manufacturer’s instructions.

5. Commissioning

When the underfloor heating and the floor are ready, the system can be put into operation. Commissioning includes:

  • Checking and adjusting the heating system settings
  • Programming of thermostats
  • System testing and operation verification

It is recommended to monitor the operation of the system during the first weeks and make the necessary adjustments.

Installing underfloor heating in connection with renovation can be a demanding project, but with careful planning and the right work steps, it will certainly be successful. You can find more information about the installation of underfloor heating, for example, on the website Rakentaja.fi.
